Answer from: ethanmoct6

$x=-\frac{15}{2}$

Step-by-step explanation:

Start by distributing the 6 to each of the terms in the parentheses:

6(x)+6(9)=9

6x+54=9

Subtract 54 from both sides

6x+54-54=9-54

6x=-45

Divide both sides by 6

x=-45/6

Divide the fraction by 3/3 since it is the greatest common factor of 45 and 6. Note we can only do this since 3/3 is equivalent to 1, so we are essentially dividing the fraction by 1.

x=-15/2

Answer from: heintzelmanvp6ir6d

$\huge \boxed{\tt x= - 7.5}$

Step-by-step explanation:

First write the equation

$\to \sf6(x+9)=9$

$\\ \\$

Divide the 6 to 9 which is multiplying (x + 9) .

$\to \sf(x+9)= \dfrac{9}{6}$

$\\ \\$

Divide numerator and denominator in right side by 3

$\to \sf(x+9)= \dfrac{3}{2}$

$\\ \\$

Subtract 3/2 with 9

$\to \sf x= \dfrac{3}{2} - 9$

$\\ \\$

$\to \sf x= \dfrac{3 - 18}{2}$

$\\ \\$

After subtracting we will get our product as - 15/2

$\to \sf x= \dfrac{ - 15}{2}$

$\\ \\$

Round of -15 / 2 to get product as - 7.5

$\to \sf x= - 7.5$

Verification:

6(x+9)=9

6(- 7.5 +9) = 9

6 × 1.5 = 9

9 = 9

Hence verified ~☆

Answer from: Quest

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

$4/2 = 2\\7/3.5=2\\8/4=2\\10/5=2$

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

$y=\frac{x}{2}$

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
